How do I generate a new OTP code from the basic information?

OTP code information

To function correctly, an OTP code requires six pieces of information:

  • The issuer: The software/service that provides you with an OTP code
  • The account: The user account linked to your OTP code
  • The secret: The value used to calculate the OTP code
  • The derivation algorithm used
  • The number of digits in the code
  • The lifetime of a code

Caution

Never share the secret of your OTP code. Anyone with this value could easily retrieve your OTP code.

Supported algorithms

OTP codes can be generated using three algorithms:

  • SHA1
  • SHA256
  • SHA512

Brennus OTP supports all of these algorithms.

Default values

Each piece of information, including the algorithm, number of digits, and lifetime, has default values. If your issuer does not provide you with this information, you can use these values:

InfoDefault value
AlgorithmSHA1
Number of digits6
Lifetime30

How to do it

To add a new code, press the + button at the bottom right of the dashboard. A selection page will then offer you the following options:

  • Scan a QR code,
  • Enter your data manually.

The second option will give you access to the form:

Once validated, the code will appear on your dashboard in the current trunk.
